Title: Control circuit for stepping motor
Inventor: KODAMA MITSURU
IPC: H02P8/22
Filed: 1994-03-18
Abstract: PURPOSE:To enable a stepping motor to cope with various kinds of exciting systems by making a control circuit to read out phase data stored in a storage device in accordance with the counting operation of a counter and output the corresponding exciting pattern. CONSTITUTION:A microcomputer 1 sets phase data expressed by eight kinds of parallel four-bit data in registers 1-8 constituting a storage device 3 in the order of exciting patterns. The microcomputer 1 gives a count value 4 to a modulo counter 2 and, at the same time, an up-count controlling signal. When the microcomputer 1 supplies a counting pulse of a required frequency to the counter 2 after setting the phase data, the counter 2 makes counting operation at every pulse and the registers 1-8 output the exciting patterns following the stepping order based on the counting operation of the counter 2. Therefore, a stepping motor can cope with various kinds of exciting system with a simple control circuit and program.

Abstract: PURPOSE: To obtain high-purity naphthoquinone, in high yield with ease and certainty, by oxidizing crude maphthoquinone (N) prepared through oxidation of naphthalene, and by distilling N with an acid content below a given value in vacuo.  
     CONSTITUTION: Hydroxy compounds, e.g. maphthohydroquinone or diquinhydrone, which are impurities and act as a polymerization accelerator, in crude naphthoquinone (N) obtained by oxidation of naphthalene are oxidized with nitric acid into quinones, and treated to give the content of acid components, e.g. phthalic or benzoic acid, of 5 mole % on less calculated as a monobasic acid based on the naphthoquinone. The crude N is then distilled in vacuo to give purified one in high yield with a slight polycondensation. The distillation is carried out at a temperature of the melting point of N to 160°C and a pressure of 1W16 Torr.

Title: Method of manufacturing cushion rubber crossing gate for vehicle
Inventor: TSUJIMOTO KATSUJI
IPC: B29C33/02
Filed: 1989-03-02
Abstract: PURPOSE:To enable the cushion rubber of crossing gate for a vehicle to be manufactured, in the nature of being less generated air bubble and having a long life time by making polyurethane into powder or particulate matter previously, and inputting it into a die after mixing with additives, and performing, while heating, degassing and molding, and then vulcanization- reacting it by vulcanization iron pot. CONSTITUTION:A main material is finished by the primary reaction as polyurethane, and in a state of powder or particulate matter. And, it is added and mixed with additives, and then inputted into a die. Since the material shows a thermoplastic property within the die at the heated condition, the air in the particles of the material is degassed completely by repeating the compression and decompression of pressing pressure. After that, it is taken out of the die and given a burring treatment, and besides left in the vulcanization pot for 24 hours for instance, and a manufacture is completed then. Inasmuch as the degassing is conducted sufficiently by repeating compression and decompression, it is noted that the degassing may be sufficient even in the molding for a cushion rubber such as being in a complicated shape having grooves 12 in upper and lower part thereof. Thus, the fatigue failure strength in the repeated compression loads between the end surface 2a of a cylinder and the flange surface 8 of the cylinder shaft is improved, and the life time thereof is prolonged, and, as a result, it may bring about the drop of impact noise and vibration due to the deformation effect of the grooves 12.
